PRINTERS RULE.

SPECIFICATION forming part of Letters Patent No. 233,704, dated October26, 1880. Application filed September 20, 1880. (No model.)

To all whom it may concern:

Be it known that I, FREDERICK ScHLEY, of the city, county, and State ofNew York, have invented certain new and useful Improvements in PrintersRules, of which the following is a specification.

The printers rules at present in general use, such ashead-rules,column-rules, and advertising-rules, are made of brass, square at thebottom and tapering at the top edge. Owing to the softness of the brassthe sharp top edge is liable to wear out quickly, so that the rules haveto be replaced by new ones. This replacing occasions frequent andconsiderable expense, especially in newspaper-printin g offices, andforms a considerable objection to the rules at present in general use.

The object of this invention is to furnish a more durable and permanentprinters rule,

which is.1n0re capable of resisting wear, and

adapted to outlast a large number of the common brass rules; and theinvention consists of a printeiis rule provided with a facing of steel,which is obtained by planing a narrow center groove into the topoftherule,insertingtherein a thin strip of steel and giving to the edgesof the same the same taper as that of the adjoining parts of the brassrule.

In the accompanying drawings, Figure l represents a perspective view ofmyimproved printers rule, and Fig. 2 is a vertical transverse section ofthe same, drawn on an enlarged scale, on line at m, Fig. 1.

Similar letters of reference indicate corre- 5 sponding part-s.

Ain the drawings represents a printers rule,

made of brass, of the usual lengths and sizes. B represents a narrowstrip of steel, which is inserted centrally into the upper part of therule by planing out a central groove of 40 corresponding size in thesame and securing the steel strip B by clamping the side lips of therule thereto by pressure. The projecting edge of the strip B is finallyfinished by being planed off at the same taper as that of the upper partof the brass body at both sides thereof, so that a printers rule with asteel edge or facing is obtained, which, owing to the greater resistanceof the steel, is more durable than the common brass rules and capable ofoutlasting a considerable number of the common rules.

Having thus described my invention, I claim as new and desire to secureby Letters Patent 1. As a new article of manufacture, a steelfacedprinters rule,-snbstantially as and for the purpose set forth.

2. In a printers rule, the combination of rule A, having a central topgroove with a narrow steel strip, B,inserted therein, and having thesame taper as the top of the rule, substantially as and for the purposedescribed.

In testimony that I claim the foregoing as my invention I have signed myname, in presence of two witnesses, this 15th day of September, 1880.
